Application filed May 23, 1927. SerialNo. 193,635

signed for escutcheons made of pottery, andv is to provide them with, preferably, metallic fastening means secured to the escutcheonin a simple manner. I

The invention is illustratedin the panyingdrawings andthe following speci fication in which preferred embodiments are shown and described. g

Fig. 1 is a fragmentary sectional view through a wall showing a side viewvof aplumbing fixture projected therethrough,

and an'escutcheon embodying my: invention concealing the opening V V Fig. 2 is a front View of the escutcheon,

drawn in a larger scale;

Fig. 3 is a vertical sectional View through the escutcheon along the plane of line 33 in Fig. 2, the plumbing fixture being indicated in outline only;

' Fig. 4 is a fragmentary horizontal sectional view along the plane of line H in Fig. 3; I

Fig. 5 is a vertical sectional view along the plane of line 55 in Fig. 3; and

Figs. 6 and 7 are views similar to Fig. 5, but each showing a modification of the tening means.

Like characters of reference denote similar parts throughout the several views and the following specification. p

10 is a wall having an opening 11. 12 is a plumbing fixture having a body 13, a tubular extension 14, a spindle loadapted to be reciprocated within the extension, and a handle 16 fastened to the spindle.

17 is a socalled escutcheon, made of pot tery, that is clay ware, molded and hardened and of vitreous surface, porcelain, or the like, a product of the ceramic industry. Escutcheon 17 comprises a round disc 18 of a diameter greater than the wall opening 11, and a tubular extension 19 at one side thereof. 20 is a round bore through the extension and disc. 21 is a groove in the Wall ofv bore It is the particular object to.

accom- 20," extending from the inner face of the escutcheon adjacent the wall to nearly the 1 front end of the bore,.leaving a. thin wall 22 at its front end. The side walls of groove 21 are made, preferably, slanting or taper-' ing as at-23, that is the groove 21 is narrower in cross section at its opening adjacent the bore 2Q than its inner wall opposite this opening, as is clearly shown in Fig. 5. 24 1s a thickened portion of the extension 19 having a bore'25 therethrough terminating within the groove 21. I

26 .ls'a screw projectingthrough bore 25 into bore .20. 27 is a lock nut, preferably, of

squareshape, in threaded engagement with screw 26. In assembling the screw 26 and nut 27 with escuteheon 17, the nut is slipped "into groove 21 through its open end and pushed toward the closed; end of the groove when its threaded center registers with'bore 25.

Attention is particularly drawn to the fact that whenwithin the groove'21 thelock nut will notdrop outinto bore 2O, because of the slanting sidewalls 23 of the groove which provide an "opening adjacent bore 20 narrower than the width 'offthe nut 27. The

screw 26 isthen inserted-through bore 25 into the lock nut 27 and extends slightly be- .yond it into thebore 20.

The escutcheon is placed over extension 14 of the plumbing fixture 12 and pushed against the wall 10 to conceal the opening 11, and when in this position, the screw 26 is screwed down tightly, its inner end'being jammed against the extension 14, effectively locking the escutcheon on the fixture and tightly against the wall. Escut'cheons, as heretofore used, employed separate jam nuts threaded directly upon the extensions 14 or their equivalents of plumbing fixtures, be cause screws obviously could not be thread ed into escutcheons made of pottery. With my construction, I eliminate these separate jam nuts and'provide simple, inexpensive and unobtrusive means to fasten the escutcheon upon the fixture. Moreover, owing to the particular shape of the groove within the escutcheon, I greatly facilitate the assembling of the nut and screw with the escutcheon and particularly prevent loss of the lock nut when disassembling for repairs and when the screw has been disengaged from the nut.

While I have shown the nut 27 of square shape, of course, any shape may be used as long as fiat surfaces are provided to be guidso I ed by the walls'of the groove to prevent rotation of the nut when screwing in the screw. Furthermore, while in Fig. 5 the side walls of the groove 21 are shown slanting, the groove may be made as shown in Fig. 6, namely with substantially parallel side walls and wide at its top, as at 23 and stepped to form a narrow opening adjacent bore 20, as at 23 or the nut may be shaped conforming if slanting side walls, as shown at 27 in lg. 7. Y

Various other modifications in form, proportion and combination of parts may be resorted to without departing from the principle of my invention as defined in the appended claims.

What I claim as new is:

1. An escutcheon of pottery to conceal an opening in a wall having a central bore adapted to pass over a plumbing fixture, a groove in the said bore extending from the wall side of the escutche'on partly through the escutcheon, the said groove having its adapted to pass over a plumbing fixture projecting through the said opening, a groove in the said bore extending from the wall side of the escutcheon partly through the escutcheon, the said groove having its side Walls so disposed as to provide a'narrower opening adjacent the said bore than its outermost wall, a metallic lock nut non-rotatably held Within the said groove, and a metallie screw extending through a transverse bore of the escutcheon and engaging and passing through the sald lock nut and a-dapted'to fixedly secure the said escutcheon upon the said plumbing fixture.

3. Anescutcheon of pottery to conceal an 7 opening in a wall, comprising a disc and a round extension at one side thereof, and hav ing a central bore therethrough adapted to pass over a plumbing fixture projecting through the said opening, a groove 1n the said bore extending from the wall side of the escutcheon partly" through the escr'itcheo'n, the said groove having its side walls so disposed as to provide a narrower opening adjacent the said bore than its outermost wall, a lock nut non-rotatably held within the said groove, a thickened portion of the said round extension having a bore transversely through the escutcheon, and a screw extendingthrough the said transverse bore and engaging and passing through the said lock nut and adapted to fixedly secure the said escutcheon upon the said plumbing fixture. In testimony whereof I have hereunto set hand.
